A Formal $\Gamma$-Convergence Approach for the Detection of Points in 2-D Images
Daniele Graziani, Laure Blanc-Féraud, Gilles Aubert · SIAM Journal on Imaging Sciences · 2010
We propose a new variational model to locate points in 2-dimensional biological images. To this purpose we introduce a suitable functional whose minimizers are given by the points we want to detect. In order to provide numerical experiments we replace this energy with a sequence of more treatable functionals by means of the notion of $\Gamma$-convergence.
